“…Total Kjeldahl nitrogen (TKN) was determined using a Kjeldahl heating block with an exhaust system (Foss Tecator 1007 Digestion System 6, Foss Analytical, Sweden). TAN was determined by distillation (Foss Tecator 1002, Foss Analtyical, Sweden), and FAN was calculated according to (Nie et al, 2015). Elemental composition was quantified using an elemental analyzer (FlashEA 1112, Thermo Finnigan, Italy).…”

“…Many approaches have been suggested for dealing with nitrogen-rich feedstock for AD, such as acclimatisation, trace element addition, dilution, and ammonia stripping (Nie et al, 2015;Niu et al, 2013). One form of dilution is co-digestion with a low nitrogen co-substrate to achieve a favourable C/N ratio and ensure that TAN and free ammonia nitrogen (FAN) remain below the threshold inhibitory concentrations.…”

“…Dilution with water, however, involves the additional costs of the water required and the subsequent treatment of substantial amounts of effluent (Nie et al, 2015;Niu et al, 2013). In addition, dilution itself cannot increase the biodegradability of feedstock or the fundamental efficiency of the AD system.…”

The feasibility of co-digestion of chicken manure (CM) and maize silage (MS) without water dilution was investigated in 5-L digesters. Specific methane production (SMP) of 0.309 L CH 4 g -1 volatile solids (VS) was achieved but only at lower %CM. Above a critical threshold for total ammonia nitrogen (TAN), estimated at 7 g N L -1 , VFA accumulated with a characteristic increase in acetic acid followed by its reduction and an increase in propionic Methanogenesis was completely inhibited at TAN of 9 g N L -1 . The low digestibility of the mixed feedstock led to a rise in digestate TS and a reduction in SMP over the 297-day experimental period. Methanogenesis appeared to be failing in one digester but was recovered by reducing the %CM. Co-digestion was feasible with CM ≤20% of feedstock VS, and the main limiting factor was ammonia inhibition.

“…Digested sludge from a stable operated CSTR reactor of Asuwei Landfi ll (Changping District, Beijing, China) was selected as inoculum. Prior to inoculation, inoculum was acclimated (pre-incubation) for two weeks in a constant temperature incubator shaker (ZWYR-D2402, China) by adding mixed KW at 42±1ºC [8][9]. Unpublished data from biogas plant surveys suggest that average temperatures of mesophilic (35-45ºC) digesters of full-scale biogas plants was 40ºC, therefore the performance of trials at 42ºC seems legitimate to us.…”

Five types of kitchen waste (KW) from China -including hop pot (HP), fast food (FF), Hebei cuisine (HC), university canteen (UC), and other mixed KW (Other) -were investigated as feedstock for potential biogas and methane production. The biodegradability of KW was measured using batch anaerobic digestion (AD) tests and feedstock at an inoculum ratio (F/I) of 0.5. Gompertz and Cone models were used to determine the kinetic parameters of KW degradation, biogas, and methane production. Results showed that HP had the highest lag phase time of 5.46 days. Methane production varies with different sources of KW. HP had the highest methane yield of 363.9 mL/g-VS added as compared to a sample of FF (334.8 mL/g-VS added ), other ( 278.5 mL/g-VS added ), UC (239.2 mL/g-VS added ), and HC (236.0 mL/g-VS added ). The biodegradability of KW ranged from 39.5% to 50.4%. During the AD process a certain amount of fl oating brown particles (FBP) were formed, which may be the main inhibiting factor of methane production. Analysis of 13 C NMR and FTIR revealed that the main component of FBP was calcium stearate. The formation mechanism of calcium stearate may contribute to the relatively high lipid content (18.6% to 30.9%) of the KW sample, which subsequently resulted in over-accumulation of long-chain fatty acids (LCFAs) and reaction with Ca . Using lipid-rich substrates as feedstock may be an effi cient approach to adding Ca 2+ artifi cially for reducing the inhibition of LCFAs.

Dedico este trabalho ao 170, onde meu sonho foi compartilhado e vivido intensamente, onde incontáveis vezes nosso sonho esteve acima de qualquer aspiração ou conflito individual. AGRADECIMENTOSA Deus.À minha família, que mesmo distante, não me permitiu sentir só e desprotegido.Através dos laços que nos são natos, esteve comigo em todos os momentos, nas conquistas e frustrações. Acreditaram em mim nos momentos em que nem eu mesmo acreditava, fizeram de meu sonho parte do seu e por inúmeras vezes sacrificaram seus sonhos para que o nosso sonho pudesse se cumprir. Carrego em meu coração todos os sorrisos e cada lágrima que essa caminhada nos custou. Meu maior orgulho é ser motivo de orgulho para vocês.Ao meu orientador, professor Dr. Eduardo Cleto Pires, cuja retidão e profissionalismo inspiram aos que o cercam. Sua presença e influência alteraram meus caminhos e devo à sua experiência e generosidade meu sucesso.A minha co-orientadora, Dra Valéria Del Nery. Sua fama e sucesso profissional me fizeram estremecer ao saber que trabalharia contigo. O que eu não conhecia era sua generosidade em ajudar quem procura trilhar uma carreira como a sua. Nosso sorriso largo e abraço apertado a cada encontro deixam clara a relação de carinho que estabelecemos.Aos professores e funcionários do Departamento de Ciências da Engenharia da Universidade de Oxford e aos membros do New College, na mesma universidade, que fizeram de minha estadia na Inglaterra um período inesquecível.Devo agradecimento especial ao meu co-orientador, professor Dr. René Bañares-Alcantara, que viabilizou a concretização do sonho de realizar estágio no Reino Unido, e compartilhou da mais incrível experiência da minha vida, a qual influencia sobremaneira no homem que hoje eu sou. Com sua sabedoria somada à sua paciência invejável com alguém que arranhava na língua inglesa, me orientou como me tornar um bom profissional e me mostrou que somos do tamanho dos nossos sonhos.Aos meus queridos amigos, cujo bom senso e polimento dignos de um lorde que sou não me permitem nominar, a fim de não cometer a indelicadeza de esquecer-me de citar um nome. Deus foi generoso ao me cercar de pessoas excepcionais, seres com mentes brilhantes e almas presentes. Dotados de energia radiante e imensa generosidade em compartilhar suas vidas e experiências comigo, tornando-me a cada dia um homem melhor.Nunca me faltou um sorriso de bom dia ou abraço de afago, nunca houve tempo para me sentir sozinho, carente de uma boa conversa, tampouco de boas risadas. Amo meus amigos, amo amá-los e não economizo amor, e em minha caminhada sempre tive abundância de pessoas a quem amar.Não seria justo, no entanto, deixar de nominar meu amigo Dr. Lucas Tadeu Fuess, pesquisador brilhante, admirado por todos, e que participou de cada linha escrita durante meu doutoramento. Precisaria de duas vidas para retribuir toda a ajuda que recebi de você, irmão. A digestão anaeróbia é uma potencial solução para a destinação dos grandes volumes de vinhaça gerada em biorrefinarias de cana-de-açúcar. A alta concentraç...
